Hi There,

I want to better understand your system. can you share following output of command line to me ?

$ cat /proc/cpuinfo | grep -i intel

$ lspci -nn | grep VGA

$ lspci -k -s 00:02.0 

And, Have you met any error during run the script (install_sdk_UMD_CentOS.sh and build_kernel_rpm_CentOS.sh) ?

Thanks,

Zachary

Hi Ildar.

Check i915 module with following command:

$ lsmod | grep i915

If the module is not loaded, try to load it manually:

$ modprobe i915

[Ildar_K_]

Hi Alexander.

i915 module loaded

$ lsmod | grep i915
i915                  938476  0

Hi Ildar.

on my machine will got following output.

lmsdk@jiandon-desk1:~$ lspci -k -s 00:02.0
00:02.0 VGA compatible controller: Intel Corporation Device 0d22 (rev 08)
        Subsystem: Gigabyte Technology Co., Ltd Device d000
        Kernel driver in use: i915
 

It looks like your i915 module is not load correctly.

let's check grub menu, please share the output of following command line.

$ cat /proc/cmdline

and let me know if you used UEFI in BIOS ?

Thanks,

Zach
